Tomo,

Thanks for all the work you've done with this driver. It is much appreciated.

What sort of performance are you seeing with this? With filebacked devices, I
was seeing around 1 MB/sec doing a basic disktest run. I haven't compared this
to ibmvstgt, but I'm pretty sure we did a fair bit better there. Perhaps I've got
some setup issue?

I tried a ramdisk device and saw this on the server:


DMA_TO_DEVICE not supported for RAMDISK_DR with task_sg_chaining=1



All my I/O on the client timed out because of this. 

-Brian
